It is a hard decision to euthanize a fish. I had neons (Paracheirodon innesi)for a lot of years, and last year I lost all of them due to neon disease. I have researched neons and talked to a lot of people on this subject. As beautiful as they are I have decided not to risk any other fish due to the neon diseases, I lost a beautiful Heros Severum due to it, and now only have one severum and dont dare get another as he is full grown and I dont think he would go for it.

Seriously, think about what you want/need to do. We are here for support and any help that we can offer.
